GLOBE STRUCTURE.

Application filed MarchlS, 1925. Serial No. 16,408.

Our invention relates to lighting fixtures and particularly to a housing for enclosing electric light units. a

The principal object of our invention is to provide a closed globe for street lighting units that is provided with means for protecting the globe by preventing moisture from running down 1t.

Another object of our invention is to provide a globe entirely of glass, which is closed in order that dust cannot collect inside of the globe and which is, however, accessible for the replacement of lamps.

Heretofore, lamp-post tops have been provi'ded with substantially cylindrical globes of glass which were mounted on the lamp-post and were surmountedby metal canopies. Another type comprised metal frame members upon which the glass walls of the globe were mounted. The top or canopy of. the latter fixture comprised frame members and panels which were either of transparent or nontransparent materiah Another form of fixture for lamp posts was a spherical globe that was secured to the lamp-post and formed an entirely closed glass unit. In all of these forms of fixtures, the sides of the globe soon became streaked from dust and from moisture running down the globe. Insome forms of globes, the walls became overheated and, when drops of moisture struck the globes,

breakage resulted by reason of the sudden cooling.

Our invention constitutes an improvement in lamp-post globes and comprises a globe or top entirely of glass, which is provided with means for protecting the globe from moisture and dust. The globe, therefore, is not streaked by the moisture which runs down from the canopy, nor is it broken by reason of drops of moisture striking the heated globe wall. The housing is made in two parts, and provides means for permitting convenlent disassembling and also replacement of lamps.

In the drawing constituting a part hereof, and in which like numerals designate like parts,

Figure 1 is an elevational view of our lighting fixture, a portion thereof being shown in section,

Fig. 2 is a plan view of a ring-shaped holder that secures the globe and canopy together, and

Fig. 3 is an enlarged cross-sectional View of the globe flange and the holder, showing in detail the manner of connecting the globe and canopy together.

Our lighting fixture comprises a glass globe 1 and a canopy 5 that are held together by a ring-shaped holder or band 7 and are secured to the lamp-post top 2 by means of screws 3. The globe may be made of either plain, stippled or opal glass, and has an outwardly flaring bell-shaped wall that terminates at the top in a flange 4. The top portion or canopy 5 is of glass similar to the globe 1, is conically shaped and has an outwardly extending flange 6 of greater diameter than flange 4 and so shaped that an overhanging ledge is formed." i

The globe and canopy are held together by a holder (which is described in detail and claimed in application Serial No. 683,902 by John R. Townsend, filed January 2, 1924, and assigned to the George Cutter Company of South Bend, Indiana). The holder comprises a band 7 having'short channel-shaped sections 9 suitably spaced apart and attached thereto by rivets 10. The sections 9 form U-shaped fingers that fit around the glass flanges 4 and 6 to hold the globe and canopy together, as best shown in Fig. 3. One end of band 7 is provided with an opening 13 into which a curved or up-struck tong ue'14 is NTJTOFFICE.

the hook 14 is disengaged. The hand then 'loosens and allows fingers 9 to disengage flanges 4 and 6.

Our lamp-housing comprises a two-part structure entirely of glass. The globe is of inverted bell-shape, so that rain or moisture falling or running down from the canopy is prevented from striking the globe. A conically shaped canopy of glass is provided with a flange that fits over the upper globe flange and forms an overhanging drip-ledge, which prevents moisture and drippage from running down the globe wall,

Although we have described a specific embodiment of our invention, we do not wish to be limited thereto, as modifications of the specific form of canopy, globe-holder or ledge may mvention skilled in the art without spirit of the invention,

be made. Other modifications of our will suggest themselves to those departing from the the scope of which is 5 defined inthe annexed claim.

We clai A lamp an outwar a top for 10 to rest union and to extend over protect t m as our invention housing comprising a globe having dly and upwardly extending flange, said globe having a ledge adapted e exterior of said globe from moissaid flange to ruary, 1925. r V
